HUGH WILLIAMSON KELLY, F WOODBRIDGE, NEW JERSEY.

{UNITED STATES TRACK TORPEDO.

Application filed July 11, 1925.

To all whom it may concern:

'Be it known that I, I-IUGH l/V1LLIAMSON KELLY, a citizen of the United States, residing in Woodbridge, Middlesex County, New Jersey, have invented Track Torpedoes, of which the following is a specification.

This invention relates particularly to track torpedoes of the type disclosed in my Patent No. 1,249,113 dated December 4-, 1917. The principal object of the invention is to provide a torpedo of this type wherein the body of explosive or detonating material is fully protected from moisture and at the same time to provide a construction which can be simply and cheaply manufactured. Other objects will be apparent from the following specification and claims.

In the accompanying drawings I have shown three embodiments of the invention, but it will be understood that the drawings are for illustrative purposes only and that various changes may be made within the scope of the appended claims without departing from the spirit of the invention.

Of the drawings:

Fig. 1 is a perspective view of a track torpedo embodying the invention.

Fig. 2 is a perspective view showing the enclosing and retaining member prior to the insertion of the detonating body.

Fig. 3 is a perspective view showing the detonating body, this being illustrated as wrapped in paper.

Fig. 4 is a longitudinal sectional view through the torpedo showing it in place on a rail head.

Fig. 5 is a transverse sectional view taken along the line 5-5 of Fig. 4:.

Fig. 6 is a longitudinal sectional View showing another embodiment of the invention.

Fig. 7 is a transverse sectional View taken along the line 7 -7 of Fig. 6.

Figs. 8 and 9 are views similar respectively to Figs. 6 and 7 but showing still another embodiment of the invention, Fig. 9 being taken along the line 9-9 of Fig. 8.

Referring to the drawings, particularly to Figs. 1 to 5, it will be noted that I have provided an enclosing means or member for a body of detonating material. This member comprises upper and lower walls 1 and 2 which are integrally joined together at their ends and are initially separated at their edges. Depending rail engaging lugs 33 are formed integrally with the walls 1 and Serial No. 42,920.

2, these lugs being so spaced that they are adapted to fit over the head of a rail, of a railroad track, and to engage the sides and bottom thereof.

The retaining and enclosing member may be made of any suitable material, although it is preferably made of rubber or of a rubber containing material. By referring particularly to Fig. 2, it will be observed that the entire member is of uniform shape and cross section from side to side, it being thus adapted to be cut from a long strip or bar extruded from a die press as fully described in my patent already referred to.

The body of detonating material is preferably contained in a paper wrapper, the package as an entirety being illustrated at a in Fig. 3. This detonating body is inserted into the space between the walls 1 and 2 and it is entirely surrounded by rubber or other non-metallic elastic material, which serves to entirely protect it from moisture. The said elastic enclosing means consists at least in part of the said upper and lower walls 1 and 2. As illustrated in Figs. 1, i and 5 no onclosing or protecting device supplemental to the said walls 1 and 2 is provided. Protection is secured by drawing together and sealing, by suitable cement or otherwise, the respectively adjacent edges of the walls 1 and 2. These walls are shown as cemented together at 55, thus providing a complete enclosing means for the detonating body.

In Figs. 6 and 7 I have shown an alternate construction wherein the walls 1 and 2 are supplemented by a tube 6 formed of ma terial similar to that of the walls 1 and 2. This tube is drawn over the detonating body 4 and the ends of the tube are sealed or cemented together as shown at 7-7. The tube with the detonating body therein is sealed in place in the space between the two walls 1 and 2.

In Figs. 8 and 9, I have shown another alternate embodiment of the invention. In this case the detonating body is put in place between the walls 1 and 2 but, instead of ccmenting together the respective edges of these walls, a tube 8 of the same material as the walls is passed over them and over the detonating body, the ends of the tube being closed and cemented to the main enclosing member as shown at 9-9.

From the foregoing description, it will be apparent that I have provideda construction which is very simple and also very effective for holding and protecting the detonating charge. The main body as shown in Fig. 2, can be extruded and even When the supplemental protecting devices are used they consist merely of short sections of inexpensive tubing.

What I claim is:

l. A track torpedo comprising in combination, a body of detonating material; and retaining and enclosing means for the said body of non-metallic elastic material surrounding the body on all sides to protect it from moisture and including a member having upper and lower Walls integrally joined together at their ends and having integrally formed depending rail engaging lugs adjacent the ends of the Walls, the said member being initially of uniform shape and cross section from side to side so that it may be formed by extrusion.

2. A track torpedo comprising a body of detonating material; upper and lower Walls ofnon-metallic elastic material enclosing the said body and integrally joined together at their ends; means for connecting the respectively adjacent edges of the Walls to prevent moisture from reaching the detonating ma terial; and depending integrally formed rail engaging lugs at the ends of the said alls.

3. A track torpedo comprising a body of detonating material; upper and lower Walls of non-metallic elastic material enclosing the said body and integrally joined together at their ends, the edges of the said Walls being cemented directly together to prevent moisture from reaching the detonating material;

and depending integrally formed rail engag-.

ing lugs at the ends of the said Walls.

4;. A track torpedo comprising in combination, a body of detonati'ng material; and a retaining and enclosing member having upper and lower walls integrally joined together at their ends and having integrally formed depending rail engaging lugs adjacent the ends of the walls, the said member being initially of uniform shape and cross section from side to side so that it may be formed by extrusion, and the edges of the Walls of the said member being cemented directly together to" prevent moisture from reaching the de'tonating material. a
